Energy spectrum-dose measuring method and device

An energy spectrum-dose measuring device, comprising:

• a spectrometer calibration module, configured to perform energy calibration on a spectrometer using a standard radiation source to obtain a conversion relation between a channel and an energy, wherein the conversion relation is represented by a calibration factor;
• an energy region grouping module, configured to measure ray peaks of n radiation sources with different energies, and divide energy of an obtained energy spectrum into n regions, wherein each region at least has a full-energy peak of one ray, and n is a number of radiation sources with different energies;
• a spectrum collection module, configured to perform spectrum collection on the n radiation sources according to the n regions to obtain n net energy spectra subjected to the energy calibration through by the calibration factor;
• a measuring module, configured to perform dose measurement on the n radiation sources sequentially to obtain n dose rates corresponding to the n net energy spectra;
• a conversion coefficient solving module, configured to calculate a relationship between counting rates of the radiation sources in the n regions and corresponding dose rates, wherein the relationship comprises n energy spectrum-dose conversion coefficients to construct an energy spectrum-dose function.
